No phantom power, trim pot doesn't work

Postby goatfinger07 » Mon Oct 02, 2017 10:40 am

I've had a CH01 with an N72 that I assembled, both of which have worked great for about 10 years now.

I finally got around to assembling an A12 1.6 that's been in the package for several years. All tests went well and I've tried reflowing all of the solder contacts, but for some reason there is no phantom power and the trim pot doesn't appear to trim the level at all. It's definitely getting 48v at the molex connector, but I haven't figured out how to trace much beyond that. Other than that it appears to work and sounds great. Any ideas for fixing the phantom and trim pot?
